CASPER FAUS'I, OF OSHKOSH, WISCONSIN.

BRIDGE-GATE.

To all whom it may concern: 7

Be it known that I, CASPER FAUST, a citizen of the United States,residing at Oshkosh, in the county of Winnebago and State of Visconsin,have invented certain new and useful Improvements in Bridge-Gates; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same. 7

This invention relates to an improved automatically operated bridge gatefor use in connection with swinging bridges for closing the roadwayapproach to travel when the bridge is turned away from its approach.

The object of the invention is to provide a simply constructed andreliable gate which is automatically closed on the opening of the bridgeand opened on the closing thereof.

Another object is to provide simple and efficient means forautomatically locking the gate in closed position operable by theopening of the bridge and for unlocking it on the closing of the bridge.

lYith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings: Figure 1 is a top plan view of a drawbridge and the :uljacent roadway equipped with this improved gate thebridge being in closed position; Fig. 2 is a side elevation with thebridge shown in open position and the roadway closed by this improvedgate; Fig. 3 is a bottom plan view thereof with the bridge in closedposition; Fig. f is a similar view with the bridge in open position;Fig. 5 is a central longitudinal vertical section thereof; Fig. (5 is asimilar view taken on the line G6 of Fig. 4; Fig. 7 is a transversesection taken on the line 7-7 of Fig. 3; Fig. 8 is a similar view takenon line S-8 of Fig. 3; Fig. 9 is a perspective view of the rack bar. Inthe embodiment illustrated A represents a portion of a draw bridge ofthe type which revolves about an axis located at its center and has endswhich are formed on curves which are concentric with said axis,

said curved ends being preferably provided with a flange B which extendsin the same plane with the upper face thereof and is adapted to overlapa similar flange C formed Serial No. 563,553.

on the lower face of the abutment D which is formed with a curved endalso arranged concentric with the axis of the bridge. The constructionof the abutments D of this well known type of bridge depends upon theexigencies of the situation and they may be of masonry, open trestlework or any other desired construction.

A swinging gate 1 is herein shown and is preferably composed of twolaterally opening members 2 and 3 which are mounted at opposite sides ofthe roadway on revoluble posts 4: and 5 which extend through the bridgefloor and through a transversely arranged sleeper 6 with their lowerends projecting through said sleeper and fixed to one end of links 7 and8. The free ends of these links 7 and 8 are preferably connected withone end of links 9 and 10 the other ends of which are pivotallyconnected with arms 11 and 12 which extend tangentially from disks 13and 14 fixed to the outer faces of pinions 15 and 16 which are pivotallymounted on the sleeper 6 adjacent the center thereof. A rack bar 17 ismounted to move longitudinally on the sleepers 6 and 6 and is providedat its rear end with a longitudinally slotted head 18 having teeth as 19arranged on the edges of the opposite sides of said head in positionto'mesh with the pinions 15 and 16 above described. The slot 20 of thishead 18 engages a depending stud 21 on the lower face of the sleeper 6which serves as a guide for said head and also as means for limiting thebackward and forward movement of the bar 17. Two de pending rollers 22and 23 are preferably arranged on the lower face of the sleeper 6between which rollers said bar 17 reciprocates and which form guides forthe front end of said bar.

An upwardly projecting stud 2 1 is secured to the front end of the bar17 and is preferably provided with a roller 25 which is adapted forengagement by a member carried by the draw bridge A for reciprocatingthe rack bar 17 on the movement of said draw bridge into and out ofclosed position. This bar 17 is also provided near its front end in itsupper face with a recess 26 for engagement by a latch member 27 mountedto move vertically on the sleeper 6 for locking said rack bar againstlongitudinal movement when the gate is in closed position; This latchmember 27 is preferably con-. structed in the form of a slotted barslidably engaged with a laterally extending stud 28 which projects fromone face of the sleeper 6. This member 27 also slides in a keeper 29which guides the latch bar and holds it against lateral movement. Thelower end of this latch member 27 is bifurcated and the arms thereof areadapted to pass on opposite sides of the rack bar 17 the crotch fittingwithin the recess 26 of said bar 17 aid lock said bar against movement.An operating finger 30 projects laterally from the member 27 and isadapted to be engaged by operating members 31 and 32 secured to theopposite sides of the adjacent end of the draw bridge or movable memberA. These members 31 and 32 are preferably made in the form of resilientplates fixed interglnediately of their ends to the lower face of thebridge member A and inclined out *ardly and forwardly from their innertoward their outer ends to provide for their engagement with the upperface of the finger 30 on the opening of the draw bridge and for theirengagement with the lower face of said finger on the closing of the drawbridge whereby said latch member 27 is moved into and out of operativeposition.

In the form shown the movable or draw bridge member A is provided on itslower face adjacent the curved end thereof with a ltmgitudinally curvedtrack member 33 arranged transversely of the member A. This track member3 -3 is preferably composed of a resilient metal plate supportededgewise on said draw bridge by any suitable means and with the oppositeends thereof curved inwardly to facilitate its engagement with the stud24lcarried by the inner end of the bar 17 and which moves said barinward and out-ward for opening and closing the gate on the movement ofthe draw bridge member into closed and open positions respectively. Tworesilient plates 3st and are supported edgewise adjacent the inner faceof the member being spaced laterally therefrom a sutlicient distance topermit the roller 25 on the stud 2 L to move freely therebetween. Theinner ends of these members 3st and are spaced slightly apart as isshown clearly in Fig. 3.

In the operation of this improved gate the parts being in the positionshown, in Fig. 1 with the roller 25 engaging the inner face of the trackmember 3?) at a point midway its length the movement of the draw bridgeA in either direction will cause this curved track to move the rack barrearwardly thereby rotating the pinions 15 and 16 a sutlieient distanceto close the swinging gate members 2 and 23 motion being imparted tosaid members 2 and 3 by means of the cam disks 13 and 1 t. arms 11 and12 and links 9 and 10 and T and S as above described. iVhen the rack bar17 has reached its extreme rearward movement the recess 26 therein willbe brought into position just below the bifurcated end of the member 27and as the bridge member A swings open the member thereof will engagethe upper face of the finger 30 and force said latch 27 downward intoengagement with said recess 26 where it will remain by gravity and holdthe gate in closed position until the draw bridge is closed when themember on the closing thereof will engage the lower face of the finger30 and raise said latch 27 out of engagement with the recess 26 therebypermitting the rack bar 17 to be moved for wardly by the track 33 andthe end members 2 and 8 to be swung into open position as shown in Fig.1.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood with out requiring a. more extended explanation.

Various changes in the form, proportion andv the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.
